Patch v3.0 for the European release (Team17 FTP) synchronizes the game to the later American version and fixes multiple bugs.
Official graphics update (Team17 FTP; not required for patches v3.5.x.x onwards)
The latest update is v3.8 (formerly at the official website and the Team17 FTP). It is a result of Team17's permission given to two community members, Deadcode and CyberShadow, to update and patch the game. Other than fixing a multitude of bugs and adding some new features, the game is now more compatible with newer systems. These patches are not compatible with some versions of the game, however (downloaded versions, such as TryMedia).
